Python virtualenv pip install MySQL-Python causing "RuntimeError: maximum recursion depth exceeded"

Question

I setup a virtualenv and then tried to install MySQL-Python using pip (after activating env). My requirements.txt is as following:

MySQL-python==1.2.5
argparse==1.2.1
pymongo==2.6.3
wsgiref==0.1.2

When I run pip install -r requirement.txt. I get some output last line of which is:

RuntimeError: maximum recursion depth exceeded

As mentioned in a post, I even ran this command to upgrade my distribute:

easy_install distribute==0.6.28

Even that didn't work. My python version (in env) is 2.7.6 and Machine is Ubuntu 14.04

UPDATE: Stack trace is as following:

Answer 1

Getting this too!

Some notes from my setup:

• Ubuntu 13.10
  • Python-MySQLdb and libmysqlclient-dev are both installed via apt-get

I also see this, which I suspect is the root cause:

x86_64-linux-gnu-gcc: error: unrecognized command line option ‘-Qunused-arguments’
x86_64-linux-gnu-gcc: error: unrecognized command line option ‘-Qunused-arguments’

EDIT:

Looks like I still get this (MySQL-Python 1.2.4) without a CFLAGS or CPPFLAGS environment variable set. 1.2.5 works for me.
